Kudzu eradication trials with new herbicides
Two screening studies in Georgia tested new herbicides as potential eradicators of kudzu (Pueraria lobata (Willd.) Ohwi). One study was conducted on a Coastal Plain and the other on a Piedmont site. Tordon 101 was applied as the standard. Those herbicides which are currently labeled for forest land site preparation and which gave control comparable to Tordon 101 (a-0.05) were Tordon K at 4 qt/A and Arsenal Applicator Concentrate at 6 qt/A, Lower rates of Arsenal, Oust + Roundup rates up to 6 oz + 2 qt/A, and Escort rates up to 8 oz/A did not yield effective control, Spike sow, a noncrop herbicide, gave control comparable to Tordon 101 when applied at rates of 4 and 6 lb product/A, An experimental herbicide, Lontrel at 2.64 qt/A, gave statistically less control than the Tordon standard. Another experimental formulation, Escort, in combination with Roundup at 1 oz f 1 qt, gave good control and appears promising for controlling kudzu invading pine plantations.
